The -b flag is normally used when configuring the server from a remote client. You can also use run.sh -b 192.168.5.78 where 192.168.5.78 is the server address (i.e. bind directly to the server's IP from the remote client). I faced the same problem and without the -b, Jboss could not be run (this only applies to managing the server from a remote location).
